These miniature license plates were issued by the Disabled American Veterans (DAV) organization. This started in the early 1940s and continued into the mid-1970s. The DAV tags were sent with a request for a contribution to support the efforts of Disabled Veterans. The DAV tags matched the owner's automobile license plate. The DAV tags were good representations of the actual license plates from each of the state. If you lost your keys with the tag attached the instructions on the back requested the finder to deposit into any mailbox. The keys would be returned to the DAV and they would then return the keys to the registered owner.
